Linux Ethernet Bridging - Apr 2007 - [Bridge] packet size

Hi,
I have just configured a Linux box with kernel 2.6.16.7 and configured two 
ethernet interfaces (with MTU 1500) in bridge mode. CONFIG_BRIDGE_NETFILTER 
is enabled.
The problem is that ping -s 1500 192.168.0.2 doesn't work from 192.168.0.1 
if the systems are separated by the bridge. Normal ping with smaller packet 
size works ok.
What is wrong? 

Best Regards
